Signs of Cow’s Milk Protein Allergy (CMPA) in Breastfed Babies

Many breastfeeding mums worry when their baby has ongoing tummy issues, eczema, or unsettled behaviour. Cow’s Milk Protein Allergy (CMPA) is one of the most common food allergies in babies, but it can be hard to recognise, especially when symptoms are delayed. Signs may include mucus or blood in stools, reflux that doesn’t improve, frothy or frequent poos, eczema that won’t settle, or a baby who is very unsettled and uncomfortable during feeds.

Because CMPA symptoms overlap with colic and reflux, getting the right guidance is key. A paediatric allergy dietitian is the best professional to support breastfeeding mums, guide a safe dairy elimination, assess symptoms properly, and create a clear plan to confirm whether CMPA is the cause. With the right help, most babies improve quickly and many outgrow CMPA in early childhood.
